Well, the kernel issue is now defintily fixed, so it shouldn't be a

I doubt this is a guvcview issue since it works fine under trusty.

Hi,
just to make sure I've added a option to guvcview to disable calls
trough libv4l2:
guvcview --disable_libv4l2
with this all ioctls will go straight into the driver, bypassing
libv4l2.
